The queue of Star Tours is a must-see for any Star Wars geek, as it pays hommage to many aspects of the classic space saga. While there are famous characters on display such as R2D2 and C3PO as well as aliens and references to locations from the films, there's one more subtle reference to something completley un-Star Wars all together and I didn't learn about it until a few years ago.
When you reach the droid room, you'll see a lot of droid spare parts as well as some droids in various conditions. Hidden among them, underneath the final part of the queue before you get to the simulators is a droid that at first glance looks like just another droid but it's actually a hidden Kermit. That's right, as in Kermit the Frog of Muppets fame. The dead giveaway are the eyes and feet, which are purposefully inteded to look like the character. When you compare the droid and the real thing, you'll quickly notice the similarities.
